Application filed January 8, 1916. Serial No. 70,975.

To all whom it may concern:

Be it known that I, OSCAR F. GRANLUND, a citizen of the United States of America, re-

of Springfield, county of Hampden, and State of Massachusetts, have invented certain new and useful Improvements in Decorating-Depositors, of which the following is a specification.

This invention relates to an improvement in decorating depositors which are used, for example to deposit chocolate or like pasty materialin the form ofa string and in various configurations on coated candies, or

cakes, for the purpose of decoration. The

improvement comprises new meansand devices for insuring the depositing of the string in a curved line with or without movement of the receptacle. 1

Fora knowledge of the machine to which this improvement is applied reference may be had to U. S. Letters Patent N 0. 1,208,328, granted Dec. 12, 1916 to Theodor Kihlgren. Only so much of the machine as is necessary for an understanding of my invention is herein shown. a

The invention embodies in its broad form the combination of a receptacle having an outlet, means to positively and continuously eject the material through the outlet including means to keep the outlet free from clogging up, with means to-change the position of the outlet with respect to the receptacle whereby the string ejectedtherefrom will be deposited in a curved line. One of the preferred forms for this purpose embodies a receptacle having a rotatable plate in the bottom thereof, an outlet in the plate ofiset from the axis thereof, means to rotate the plate and agitating'and expelling means operable during the rotation of the plate to eject the decorating material in a string.

The objects ofthe invention will appear from the following detailed description and moreparticularly from the annexed claims.

For the purpose of illustration, a single embodiment of the invention is shown in the accompanying drawings, in which- Figure 1 is a fragmentary longitudinal section showing the invention as applied to a stringer;

Fig. 2 is a bottom plan view thereof; and Fig. 3 is a detail sectional view drawn to an enlarged scale; 1 Referring to these drawings and particularly to Fig. 1, A represents a container for the decorating material which container is adaptedto be supported above a traveling belt carrying candies to be decorated. Within this member A, a chocolate tank a is formed, and at the bottom of the tank are a series of cylindrical wells of a number equal to the number of rows of candies on the belt. Concentrically mounted in these wells a are double helical bladed sleeves 1 which are secured by the set screws shown, to other sleeves 2. The latter are suitably journaled as shown in the upper portion of member A and have keyed thereto gears 3 which intermesh, forming a train. This gear train may be driven from any suitable source of power in any desirable manner, and it has not been thought necessary to illustrate such connections as they are not essential to a full understanding of the invention.

Loosely mounted within the sleeves 2 are rods 4 which extend upwardly above the container A and have an upper portion 5 of somewhat reduced diameter. Supported above the container A and in parallel relation therewith is a plate 6 which has a depending boss having a hole 7 therein. Loosely fitting within the latter is a stud 8 which has a nut 9 thereon arranged to engage and support the lower face of theboss; Although only one of these supporting devices is illustrated, it is to be understood that there is another similar device at the other endof the container. Loosely mounted on the portions 5 aresleeves 10, which have squared exterior surfaces 11 and lower threaded portions 12 to engage in plate fins shown. The sleeves 10 are held axially by the flanges on spindles 4 and collars 13 and are arranged, when turned, to elevate the spindles t relatively to plate 6. Slidably mounted on the squared portions 11 are gears 14 which intermesh, forming a train. These gears are arranged to be turned by hand vertically to adjust the spindles, and, 0bviously, one gear may be turned to adjust all the spindles simultaneously'or an individual gear may be moved upwardly out of mesh and fixed coacting cams arrangedbelow the ratchet l6 and operative to raise the latter into engagement with the pawls 17' when deranged to act on a pin 21 normally to hold the plate 6 against stop 9. It is'to be un-' derstood that a similar ratchet structure is provided at-the other end -of the container although only one has beenillustrated. The cam elements 18 and 19 are not shown in full 4 detail as this device to raise and lower: the ratchet ;16 1 is the usual onean d is wellknowninth'e art. Theratchet 16. thus provides a means for imparting a-continuone and, rapid vertical vibratory motion to platedand allbfthe spindles 4:. ,yseciireditdtlie-first and last screw 1 are sprockets ;22 (one only .beingshown). which bear-a chain- 2-3, whereby the chocolate within the, tank ,a ,is kept thoroughly stirred. The, screw agitators 1- also assist inthe thorough stirring. of the chocolate and force the latter; downwardly into the wells 7) to be expelled' infa manner to-bed'escribed.

Referring more particularly to Fig. 3, each well?) isclosed at the bottomby a cireular, plate 3 25 having gear teeth 26 in the periphery thereof. The gears thus formed intermesh in a train ;as best shown in Fig. 2,, and this train may be driven by-any suitable means (n'otshown'). Each plate 25 has an ann'ularagroove therein which engages a corresponding fiange 27 on the lower face of the: container- -A, and the several gears are held against these bearing flanges by a grid 2g8- -secujred a'sshownin Fig.2 to the bottom ofitlre container A. I

' Fgormed eecentrically in each plate 25 is a conical depression 30 having an outletaperturfeat itslowen end. Resting in the latter isa spindle 31 which-has a tapered lower end. This spindle is rotatably supported in an upwardly extending ofi'set arm- 32integ-rallyiformed withiplate 25 andfixed to thewupperend of the spindle 311is aupinion 33. Y The lattermeshes with anannula'r gea'r 84' formed in-the-lowerend of'tlie bladed screw 1 whereby the rotative -movement of the latter is transmitted to' the spindle32. Thei rod 4, heretofore described, has its lower 1 end bent i and formed with a fork -35 which loosely enga es the spindle' 32'and supports the latter by bearing'in under the flange-of the pinion 33, as shown.

' "In operation, the chocolate in the vat a is forced downwardly by the revolving bladed screws 1. The spindles 31 are adjusted for aasuitable opening by v the threaded sleeves IO'lalready described, -an'd' these spindles are constantly vibrated 'a-Xially, whereby, in conjunction with the screws-l, thech'ocolateis positively expelled in a string; The 'gear connection-33 insures a constant rotative movement" to keep the outlet 30 at all times clear. As the chocolate iscontinuously ex pelled in string-like form, the plates 25 are continuously rotated, whereby the string is rations involving circular movements. Ob- 'viously by varying the speed of-the gears 26 and maintaining a uniform rate of travel for the conveyor, these configurations may be varied as desired in-a now well'known manner; By providing a-flexible drive for thegears'26 the receptacle may move atthe same time the-plates 25'rotate and-thus the material-may belaidin a large number of variously decorative forms.

The invention may be carried out in other forms than the one herein specifically shown and'described. The scope of the-invention ispointed out in the annexed claims.
